STOP-MOTION FOR WINDiNc-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 564,218, dated July 21, 1896.

Applicatiol filed September 23,1895. Serial No. 563,306. (No model.)

To all whom it may concern:

Be it known that I, MAR() V. PALMER, a citizen of the United States, and a resident of W illimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Stop- Motions for VVinding-Spindles, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a machine for winding thread into a cop, bobbin, or other mass with means for controlling automatically the winding operation; and my invention consists in details of the several devices making up the winding and the clutch parts and connections and the combinations of such parts, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a top or plan view of part of a winding-frame, showing one spindle. Fig. 2 is a detail view, in side elevation, of a winding-frame, showing my improved winding mechanism. Fig. 3 is a detail end view, in vertical section, through part of a winding-frame7 showing the adjustable pulley. Fig. 4 is a view in longitudinal section of the spindle, showing the clutch parts disengaged and on enlarged scale. Fig. 5 is a detail view, in longitudinal section, of a portion of the spindle, showing the clutch parts in engagement and on enlarged scale. Fig. 6 is a side view of a portion of the frame of the machine, showing the stop mechanism on enlarged scale and in position to cause the clutch parts to be engaged. Fig. 7 is a like view showing the stop mechanism in position to disengage the clutch parts. Fig. Sis a detail view showing a modification of the bent lever.

In the accompanying'drawings a part of .a winding-frame and one winding-spindle and its connected parts are shown as embodyingall that is required for a full understanding of the nature and extent of my improvement.

The letter' a denotes a frame or table arranged to support one or more winding-spindles h and the spindle-driving mechanism.

The spindle b is mounted in suitable bearings on the frame of the machine, and bears on its outer end an eXpansible tip b', around which the thread c is wound to forma cop or bobbin. The construction of this tip and its manner of attachment to the spindle maybe after any of the well-known forms, and as it forms no part of the invention a detailed description herein is deemed unnecessary.

A sleeve d is secured to the spindle b and a driven section e of a clutch device is se- 6o cured to this sleeve. This driven section c is preferably formed to bell shape, as shown in the drawings, the edge of which is slightly beveled and lies within the flange of the driving-section e of the clutch device. The inner surface of the iiange of this driving-section is beveled to yfit the beveled surface of the driven section, and the outer surface of the driving-section is grooved or otherwise suitably formed to receive a belt or like part 7o for rotating the clutch parts.

A collar c2 is secured to a hub of the drivingsection e', forming a groove c3, in which is located a flange f2, formed on the inner surface of a hollow hub or sleeve f of a hand-wheelf. The inner surface of the hub of this handwheel is threaded, as shown in Figs. 4. and 5 of the drawings, this thread fitting the thread on a spindle-.collar g, secured to the spindle b. A spring g is located in an annular recess 8o in the spindle-collar g, one end of the spring being secured to said collar and the other end to the hand-wheelf, the tendency of the spring being to rotate the hand-wheel on the spindlecollar, which rotation causes said hand-wheel to be moved toward the clutch device, the end of the hub or sleeve f thrusting against a shoulder on the driving-section c. This forces the two sections of the clutch device into engagement and causes the spindle to be rotaoo ted with the driving-section e.

Around the hub f of the hand-wheel f passes a band-brake h, one end of which is secured to an arm 7l of a bent lever c' and the other end to a band-brake bracket k, mounted on the frame of the machine. The brake is secured to one end of a rod k', that passes through the bracket, the opposite end of the rod bearing an adj usting-nut k2, by means of which the rod may be moved in the bracket roo and thus provide an adjustment for the tension of the band-brake on the hub of the handwheel The bent lever t' is rotatively mounted in a lever-bracket Z, secured to the frame of the machine, and the end 213 of the arIn i2 of this lever is so formed as to engage the thread c when the parts are in position for winding a bobbin. This bent lever forms a sort of bellcrank lever, one end of which is secured to the band-brake 7L and the other end adapted to rest in contact with the thread of which the bobbin is being formed. The arm i2 of this bent lever may be of such a weight as to cause the band-brake 7L to bind with sufficient force upon the hub f of the pulley f, or a spring 1l* (see Fig. S of the drawings) maybe used for this purpose.

To the opposite end of the spindle Z) from the tip ZJ is secured a cone-pulley h2, a belt passing around this pulley and around an equalizing-pulleym. This equalizing-pulley m is secured to an equaliZing-shaft fm', mounted in an equalizing-bearin g 171,2, adj ustably sccured to a support n, fastened to the frame of the machine. The equalizing-bearing m2 is mounted on a hub of the support n and concentric with the axis of the cam-shaft o, one end of which is mounted in the bracket n and the other in a suitable bearing on the opposite side of the frame of the machine. This equalizing-bearing 'm2 is divided, as shown in dotted outline in Fig. 2 of the drawings, nuts m3 being used for clamping the bearing to the hub of the support in any desired position. The object of this equalizingbracket is for the purpose of allowing the belt to be used on any of the different faces of the cone-pulley for the purpose of varying' the speed at which the cam-shaft 0 shall be rotated. A pinion m4 is secured to the equalizin gshaft m and is in mesh with a gear o', secured to the cam-shaft o.

The opposite end of the cam shaft bears a cam p, and a traverser q is pivoted in operative relation to the cam, the traverser having a bearing on the face of the cam at two points located on opposite sides of the pivot of said traverser. The opposite end of the traverser is suitably formed to receive the thread c and guide it back and forth along the bobbin being formed on the machine, the traverser also having a movement toward and from the bobbin. This construction of traverser and cam is of a well-known construction, forms no part of the present invention, and a further and detailed description of the same is deemed unnecessary herein.

The operation of the device is as follows: The thread c passes upward from the spool r in front of an idler s, around the idler to the under side, and thence onto the bobbin being formed on the spindle Z). The end i3 of the `arm 'i2 of the bent lever t' is located between the loop thus formed and the periphery of the idler s, as clearly shown in Fig. 2 of the drawings, this end of the lever resting upon that part of the thread located between the idler s and the bobbin. Upon the breaking of the thread c this end 3 of the arm is freed from engagement with the thread and drops downward, throwing the opposite end of the bent lever over and tightening the band-brake 7L upon the hub f' of the handwheel f. The impediment thus formed to the rotation of the hand-wheel f causes it to travel along the thread on the spindle-collar g, carrying with it the driving-section e of the clutch device, thus separating the two clutchsections and stopping the rotation of the spindle b.

The clutch as such .is operative 'to perform its function without regard to the special purpose for which the spindle or shaft is driven, and may be used in connection with other mechanism than winding machinery.

I claim as my invention- 1. In athread-winding apparatus, th-e combination of a winding-spindle havinga screwthreaded portion, g, a clutch-section e carried by the spindle, another clutch-section e loose upon the spindle, a rotatable hub or sleeve j" having a screw-threaded portion which engages with the screw-threaded part of the spindle, and which is in engagement with and operates the clutch, a band-brake which surrounds the said hub or sleeve, and a lever connected at one end to the said brake, and its opposite end being in engagement with the thread being wound so as to operate whenever the thread is slaekened, substantially as set forth.

2. In a thread-Windin g apparatus, the combination of a winding-spindle having a screwthreaded portion, a clutch device carried by the spindle, a threaded rotatable hub or sleeve engaging with the threaded portion of the spindle and adapted to operate the clutch, a coiled spring g connected at one end with the said hub or sleeve and tending to turn it so as to cause engagement of the clutch parts, a brake which operates upon the said hub or sleeve and brake-operating mechanism adapted to be operated upon the slaclcening of the thread being wound, substantially as Set forth.
